What is the value of x

1 answer:

5 0

X=3

Explanation:

A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180

56+4x+112=180
168+4x=180

Subtract 168 from both sides

4x=12

Divide 4 from both sides

X=3

You can check by filling it in.

56+4*3+112=

12+56+112=180
